Follow up on the treewide Clippy lint series [1]. The Rust Binder driver
retains local allows for `clippy::ptr_as_ptr`, `clippy::ref_as_ptr`,
`clippy::as_underscore`, and `clippy::cast_lossless` even though those
lints are enabled for the rest of the kernel.
Fix the Binder violations and remove those allows one lint at a time.
The first patch replaces Binder pointer-to-integer conversions with
calls to the strict provenance APIs now that they are available at the
Rust MSRV.
